Just incase anyone else is wondering, with Tomi's help I managed to find a utility that extracted the multis from the verdata just fine. As this thread is for Turley's app, I wont post it here unless he says its ok to do so, but if anyone needs info on it, PM me.

I got a problem while trying to replace landtiles. UOFiddler says that it supports .tiff files, but when I try to replace an existing landtile with a new one which are in .tif (which is the same as .tiff? the ending of the file-name seems to be .tif but windows says it's an TIFF-picture, I dont know.) Anyway the picture doesnt show when you want to replace it. What should I do to make it work? Thanks

Another problem I have is when I wanna change the skillgrp file. If you go to the SkillGrp Tab in Fiddler and click, for example, "Remove Necromancy" -> Save -> Replace the existing skillgrp file with the new one -> Restart UOFiddler and the Necromancy-skill is still under the Misc category in the SkillGrp tab.

About your tiff problem: no problem here, did you compare an exported tiff with your tiff?
About skillgrp: you cannot completely remove a skill from it every "non sorted" skill will be placed in misc group, you also cannot remove the misc group like the other groups, note the different color

I didn't try to do that with the tiff-files, but I saved my terrain tiles in .bmp instead and then it worked fine. But I got a new problem. I added a few new terrain-tiles and they dont seem to merge like the other tiles does (for example grass). Instead they are just placed in 1 z-level and you cannot "bend" the tiles. How can I fix this and how can I name terrain-tiles?

Thanks!
Do you have any plans on making more function in the Skill tab? Like removing skills for example Also does someone got a good tool for modifying skills.mul/skills.idx? There are one on http://ultima.lonet.cz/download.php named "Skill tools", but it wont allow custom made skills.mul/skills.idx which has less than 52 skill entries. My server got 51 entries

I would really like a tutorial of how to edit new animations. The docs of UOFiddlers sub-site at Polserver.com just won't tell me enough. I use UO:ML and I wanted to implent the Hydra animation (Graphic 265) and the Banshee Animation (Graphic 310 & 747). I found that the Hydra animation was already implented by simply changing the graphic of a zombie ingame. The attacks and death animations works fine. But when I try to change the zombie into a Banshee it will take the form of a wraith altho the animation 310 & 747 shows the Banshee animation in UOFiddler under the "Animations-tab". I did some re-search and among the "Animations-tab", "Animation Edit-tab" to see if I could find something that would give me a clue why the banshee animation wont work. This is what I found:
